title: Mean platelet volume in pseudoexfoliation syndrome and glaucoma.
abstract: OBJECTIVE
  Pseudoexfoliation (PEX) syndrome (PES) is characterized by the widespread deposition of abnormal extracellular fibrillary material on many ocular and extraocular tissues. The objective of this study was to evaluate the association among PES, PEX glaucoma (PEG), and mean platelet volume (MPV).
  
  
  METHODS
  Forty patients with PES (mean age 62.6 ± 7.8 years), 31 with PEG (mean age 65.9 ± 6.6 years), and 37 healthy individuals (control group) (mean age 64.0 ± 7.1 years) were included in the study. The MPV of the 3 groups were compared.
  
  
  RESULTS
  Age and sex distribution were similar among groups (p>0.05). Mean MPV in PES, PEG, and control groups were 9.59 ± 0.94 fl, 9.53 ± 0.80 fl, and 7.7 ± 0.67 fl, respectively. In the PEX group, MPV values were significantly higher than in the control group (p<0.05). However, there was no difference between the PES and PEG groups (p>0.05).
  
  
  CONCLUSIONS
  The MPV values in both groups with PEX were higher than those in the healthy group.
